Figure 100 Camera module bottom view including serial numbering
The camera module as a component is not a repairable part, meaning that the components inside the module
may not be changed. Cleaning dust from the front face is allowed only. Use clean compressed air.
The camera module uses socket type connecting. For versioning, laser marked serial numbering is used on
the PWB.
The main parts of the module are:
• Lens unit including lens aperture.
• Infrared filter; used to prevent infrared light from contaminating the image colours. The IR filter is glued
to the EMI shielded camera body.
• Camera body; made of conductive metallized plastic and attached to the PWB with glue.
• Sensor array including DSP functions is glued and wire-bonded to the PWB.
• PWB, FR-4 type
• Passive components
• Camera protection window; part of the phone cover mechanics
• Dust gasket between the lens unit and camera protection window
Dynamic camera configuration
DCC (Dynamic Camera Configuration) is a system to allow final camera tuning values to be programmed on
Service Centre. DCC data generated for a camera hardware is set by Camera Entity IQ department and placed
into global DCC settings database. Service centres could replace a defective module with a spare one to get
camera function recovered by updating DCC data.
DCC data update instruction
Service software is used to update DCC data when camera configuration (a camera or a hardware accelerator)
of the terminal has been changed. Service software DCC update feature reads camera configuration
identification from the terminal, selects a new configuration data file from DP (data package) and writes
data into the memory of the terminal during the process. If the update fails, new camera configuration
installed into the terminal is not supported by DP. Always update DCC when a camera or a HWA has been
changed.
